Xanthoria polycarpa forms compact mounds; X. candelaria has erect coarsely sorediate lacerate lobes; Xanthomendoza hasseana and X. montana both form rosettes (not colonies like this); X. ulophyllodes and X. oregana are coastal things very rare in the interior mountains and have broader lobes anyway; X. galericulata has these funky convex erect lobes. Only thing left is Xanthomendoza fulva, which forms large colonies with tiny narrow (but flaring) flat lobes just like this.

[forgot X. fallax, but it should have broader lobes, too, but look for the birds-nest soralia where the soredia burst from between the upper and lower cortices at the margins, I don’t see anything close in this photo]

Thanks Byrain.

Maybe Jason or one of the other lichenologists would know without looking at the rhizines on the underside (They can be small…)?

In the mean time maybe these will help…
